We are building a branch location with a few hundred users; The HQ location is connected to the branch location with a 10Gbps wavelength point-to-point circuit from $ISP1 and a 1Gbps VPLS point-to-point circuit from $ISP2.
The branch is physically less than a mile away from the HQ location and latancy on either path is < 1MS.
We have Aruba 2930F access switches, 5406R campus core switches, and 3810M datacenter top of rack switches. Topology will be:
[2x palo alto VM100's as gateway routers for all vlans] | [Stack of 2x 3810M switches in datacenter top-of-rack] | | [10G-Wavelength] [1G-VPLS] | | [VSF Stack of 2x 5406R ZL2 switches as Campus Cores] | | | [Access Stack 1] [Access Stack 2] .... [Access Stack N]
The Palo Alto VM100's are the gateway for all access vlans.
So my question is, should we stretch our vlans across the 10G Wave and the VPLS, and use STP to block the 1G VPLS?
Or, should we route across the wave and the VPLS and run VXLAN across the routed underlay?
Another approach?
How would you handle this where you have a branch location with 2 different sized links back to HQ, and the campus location has NO routing, DNS servers, DHCP servers, or anything other than L2 switching?
